Calzaghe delays defence

Joe Calzaghe has withdrawn from his projected WBO super-middleweight defence in Manchester on 11 February.

The Welshman is now scheduled to return in March having cited lack of preparation time for the contest, against an unnamed opponent.

It had been hoped Calzaghe would headline the historic pro-am bill along with Olympic silver medallist Amir Khan. Manchester's Stephen Foster is due to contest the WBU featherweight title on the same card.
